Abstract: A receptacle comprising a flange closure, consisting of a bottom part, in particular a meal tray (12), comprising a bottom, side walls adjacent thereto as well as an edge flange (22) which surrounds the top edge thereof and is directed outwardly, and further consisting of a cover (28) as a top part consisting of a foil material in the form of a rectangular foil blank (10), the four corners (14) thereof being folded around fold lines (16), which obliquely extend to the edges (18) of said foil blank (10), onto the top side thereof for forming pull flaps (20), and the sides thereof which, when laid on the bottom part, project parallel to said edge flange (22) being flanged downwardly around said flange on all sides and pressed together with the same, said edge flange (22) of the bottom part (12) of said receptacle comprising bevel corners (24) which extend substantially parallel to said fold lines (16).
Abstract: A method and apparatus for producing rectangular lids with a folded tear tab at each corner from a continuous web of foil using a cutting device to cut a generally perpendicular incision opposite each other in each edge of the foil web, a folding tool having two angled folding edges running toward each other in a direction toward the middle of the foil web and intersecting at a point in the cutting plane of the cutting device that folds the areas of foil on both sides of the incision back on themselves to form two tear tabs, and a cut-off device to cut the foil web into discrete lengths in continuation of the cuts in the edges of the web to form the lids.
Abstract: The invention relates to a flexible hose formed of a wound web material and having its walls reinforced by wire windings, with the edges of successive web windings overlapping one another. In accordance with the invention, the longitudinal axes (Da) of the wires (13, 13', 13") and the longitudinal axis (ba) of the web material (3) extend at equal inclination with respect to the hose axis (A), and the reinforcement consists of at least two wire windings.
